Need to be clearer about specifying time ranges using timestamps.
Legacy syntax which predates the date prefix is still supported, but
timestamps used in conjunction with the date prefix require additional
syntax.

If specifying a time range using timestamps in conjunction with the
date prefix, each timestamp must be preceded by @ (ASCII hex 40). As

date:<expr>..! can be used as a shorthand for date:<expr>..<expr>. The
expansion takes place before interpretation, and thus, for example,
